Web1 nov. 2024 · Stimulation of the nociceptors’ open voltage-gated ion channels allow calcium and sodium ions to pass into the cytoplasm, raising the resting membrane potential (around –65 mV) downstream until the threshold potential (around –40 mV) is achieved, leading to action potential formation. Web11 jun. 2024 · Introduction. Anesthetic gases selectively block consciousness, sparing non-conscious brain activities, and thus their mechanism of action could reveal how the brain produces, or mediates, consciousness. Anesthetic gas potency correlates with solubility in non-polar brain regions, recognized as 'pi resonance' electron clouds of aromatic amino ...
